You can use for loops in Python when you want to perform the same action with every item in a list.
fruits = ['apple', 'banana', 'pear', 'orange']
for fruit in fruits: print(fruit)
applebananapearorange
In the for loop, we retrieve an element from list fruits and store it in the variable fruit.
Then we print the element we just stored in the variable fruit.
Finally we repeat the above for all the remaining elements in the list.
NOTE
In this case we used variable name fruit, however, you can use any name that you want here (although it is better to use a meaningful name that logically represents a single item in the list).
Each indented line is treated as being part of the for loop and is executed once for each element in the list:
Do you like apples?Yes, I like apples.Do you like bananas?Yes, I like bananas.Do you like pears?Yes, I like pears.Do you like oranges?Yes, I like oranges.
